In the Mojave Forum someone suggested Launchpad Manager but this did not work for me, just reported that the download version will not run on Yosemite and as I am running High Sierra I figured there was a bug.
I do miss this feature but I am retraining myself to get around the problem, mostly as I am now using spotlight more by hitting Cmd-Space and then typing the name of the application I want which is proving pretty effective for me.
Alternatively I have also dragged the applications folder down onto the Dock next to the default Downloads folder, just make sure it is set as a Stack and sorted in Name order and when I click on it all my apps are there in alphabetical order and I never have to run the terminal command to re-sort.
